[Ffmpeg-devel] Reading a yuv file and performing h263 encode with ffmpeg
Tue Apr 19 18:06:54 CEST 2005
I want to use ffmpeg to do h263 encoding of a file which contains YUV
I saw the libavcodec/apiexample.c of ffmpeg.
They have there an example of encoding a YUV picture which they
generate in the code itself (in apiexample.c in video_encode_example()
builld an AVFrame called picture from memory).
In that example, the building of this AVFrame instance seems not to be
there are some loops there which are not clear and I cannot understand
what should I do when reading the YUV file in otder to build the
Now I want to read from a yuv file and perform encoding ; Is there
some example/application which does it ?
I had tried to do it from the command line ,on Linux, and it was OK.
What I tried is
./ffmpeg -y -s cif -vcodec h263 -i in.yuv 263decoded.yuv
But when I tried to do reverse engineereing and to learn the code and do
the same , I failed; maybe because I am trying to do it on windows;
In fact,All I want to do is read a yuv file and build from it the AVFrame
Any idea ? Is there some example / a simple app doing it?
Any help will be appreciated.
